Lost Exotic Tortoise from Tower Bridge Greater London SE1

This lost Tortoise Exotic was last seen around Tower Bridge Greater London SE1

Larrie is a female, four-year-old Hermann's Tortoise, approximately eight inches in diameter. She has been missing for little under one week. Although it is possible she is lost, we suspect she has been stolen.
My home and surrounding areas have been searched extensively, around the SE1 (Tower Bridge, London) area. My daughter has been in contact with Southwark Council, RSPCA and multiple missing pets Facebook groups to help find her.
